I need to make a crosshair (on a nonscaling, non paralax UI layer) that can stay perfectly locked on to(put itself perfectly on top of) objects which can each be on any of the other layers...and each layer has a different scale and parapax amount.

I thought I had it by using LayerToCanvas, but this only works with the projects "Fullscreen in Browser" mode set to "off". Any of the scale modes, the crosshair no longer lines up with the objects that its "locked onto"
